Core Advantages
1. Reliable Power Output & Stable Fuel Performance
Powered by CAT 3066T turbo‑charged diesel engine, delivering net power 95 kW (128 hp) @1800 rpm, displacement 6.4 L. Proven durable engine structure adapts well to poor‑quality fuel in different regions. The 340 L large fuel tank supports long continuous working hours and reduces refueling frequency. Operating weight reaches 19 400 kg, delivering powerful digging force for earthwork, rock‑soil excavation and truck loading tasks.
2. Mature Hydraulic System & Solid Working Performance
Adopts load‑sensing pilot hydraulic system, offering smooth operation and accurate control for digging, lifting and dumping. Key performance data:
- Maximum digging depth: 6 640 mm
- Maximum ground‑level reach: 10 640 mm
- Maximum dumping height: 6 570 mm
- Standard bucket capacity: 0.92 m³（range 0.8‑1.2 m³）
- Hydraulic relief pressure: 34.3 MPa, main pump flow:185 L/min
Two‑speed travel system: 0‑3.4 km/h low speed, 3.4‑5.5 km/h high speed. Sealed heavy‑duty undercarriage resists mud and sand, lowering wear of track and rollers.
3. Practical Operator Cab for Daily Work
ROPS‑certified cab with ergonomic layout and intuitive pilot handles to lessen fatigue during long shifts. Large glass windows provide good site visibility. Vibration‑reduced mounting lowers noise and shaking inside cabin. Adjustable suspension seat supports long‑time operation. Optional air‑conditioning kit available for hot‑climate regions.
4. Heavy‑Duty Structure & Low‑Cost Maintenance
Boom, stick and main frame use high‑strength thick steel plate, anti‑impact for heavy earth‑moving. Key hydraulic joints adopt reliable sealing to resist dust and leakage. All service points including filters, oil ports and inspection openings are externally arranged for quick inspection and repair. Spare parts are widely available globally, cutting repair time and ownership cost.
5. Good Attachment Compatibility
Quick coupler supports fast switching of various work tools:
- General buckets, heavy‑duty buckets, rock buckets (0.8‑1.2 m³)
- Hydraulic breakers for demolition
- Thumb grapples for scrap and bulk material handling
- Augers for hole‑drilling
Multi‑tool configuration allows one machine to finish excavation, breaking, grabbing and foundation work, improving machine utilization.
